Sequence, in 2 expression current generation sections, equipment is carrying out the renewal of data and program (is A by information characteristics code
Data and program be updated to data and the program that information characteristics code is B), data and program now are
Incomplete, it is labeled as X, the number that in 3 expression current generation sections, equipment uses information characteristics code to be B
According to and program.
In the stage 1, data and program that three redundance units all use information characteristics code to be A normally work,
The information characteristics code of the overall output of system is calculated by the majority voting of two from three by the output of three redundance units
Method is defined as A.
When after the downloading process that download manager completes the data to equipment and program, it may be determined that redundancy sets
Standby update sequence, the entrance stage 2 update one of them equipment (such as 1# equipment) data and
Program.
In the stage 2,1# equipment is carrying out the renewal of data and program, data therein and the state of program
Representing with X, data and program that 2# and 3# equipment then uses information characteristics code to be A normally work, now
The overall output of system is defined as A by the output of 2# and 3# equipment, thus the information of the data of system output
Condition code remains as A.
It is to say, in the stage 2, the number having updated output data is 0, do not update the individual of output data
Number is 2, so, system is output as the output data not updated.
In the stage 3,1# equipment is complete renewal, and the condition code of its data and program becomes B, 2# equipment
Carrying out the renewal of data and program, its information characteristics code be X, 3# device using information condition code be A
Data and program normally work, now system output by 2# and 3# equipment output decide by vote determine because
The quantity of A and B is 1, therefore, it then follows the principle of " from old ", data system exported and program
Information characteristics code be defined as A.
In the stage 4,2# equipment has been completed renewal, and the condition code of its data and program has become B,
Data and program that 1# equipment also uses information characteristics code to be B normally work, and 3# equipment is carrying out data
With the renewal of program, therefore the data of system output and the information characteristics code of program are B.
In the stage 5, three equipment all complete the renewal of data and program, and its information characteristics code is B,
Therefore, system is output as B.
Based on 5 above stages, when updating appearance and being abnormal, such as in the stage 3,2# equipment occurs more
New abnormal, do not interfere with the normal of miscellaneous equipment yet and update and work, the voting of system output still will not
It is affected.Therefore, the method described in the present embodiment is used to carry out data process, it is possible in renewal process
In when breaking down, the system that remains able to ensures correctness and the safety of output result.
